There’s a saying that goes, “He who can, does. He who cannot, teaches.”

Well, label this one the Colin Kaepernick Tweak: “Those who can, play. Those who cannot, cash in on crying.”

Kaepernick, king of the whine, prince of the protest, leader of the false narrative, has just scored a book deal. A $1 million book deal, no less. What a sham. Like Kaepernick can write? His claim to fame is this: He cries.

But all the fans go: Hey, if that’s what it takes to shut him up, it’s money well spent.

Ian Mohr of Page Six first reported the agreement — a Random House imprint One World deal with more than $1 million.

Maybe the money will help Kaepernick hire some good legal counsel to fight for the grievance he filed against NFL team owners, alleging they conspired and colluded to keep him from being signed this season.

But maybe not.

Kaepernick’s a football field has-been. His play was hardly up to par — hardly competitive — when he first took bended knee during the playing of the national anthem in August of 2016. And when he wore his famous pig-police socks? His quarterbacking talent was already a thing of the past.

His protests against supposed targeting of blacks by police have since made him a hero to the Black Lives Matter movement — a movement whose key players now want him to lead. So it looks like Kaepernick may be entering Phase II of his work world, one that piggybacks off his football fame and launches him into a season of social justice activism. Paid social justice activism, if this book deal is to be believed.

So be it. Everybody needs to make a living.

But if Kaepernick behaves as an author the same way he’s behaved as a football player, then watch out, world. When people don’t buy, he’ll be suing.

We’ll all be accused of colluding with each other to not purchase his book.
